摘要

Field experiments were conducted at the experimental area of Punjab Agricultural University, Ludhiana from 2003-04 to 2005-06 on loamy sand soil. Post-emergence (35-40 DAS) application of triasulfuron at 15 g/ha (with and without 1% surfactant) and 20 g/ha alone as well as carfentrazone-ethyl 20 and 25 g/ha controlled broadleaf weeds in wheat very effectively and produced grain yield at par with the already recommended herbicide i.e. 2,4-D 0.5 kg/ha. On an average of three years, highest grain yield was recorded in plots treated with carfentrazoneethyl 25 g/ha closely f. b. triasulfuron 20 g/ha, triasulfuron 15 g+1% surfactant and 2,4-D 0.5 kg/ha and compared to unweeded check these treatments increased wheat grain yield by 57.9, 57.3, 56.2 and 53.7%, respectively.
